<h1 class="topictitle1">备份虚拟机时，虚拟机所在ESXi主机配置了NFC backup属性的VMKernel网卡，导致备份任务失败</h1>
<div><div class="section"><h4 class="sectiontitle">现象描述</h4><p>虚拟机备份或磁盘备份时，备份任务失败。任务详情提示“通知客户端完成磁盘备份任务失败”，客户端所在主机日志中出现“Failed to connect to <em>xxx.xxx.xxx.xxx</em>:902”错误。其中<em>xxx.xxx.xxx.xxx</em>为虚拟机所在ESXi主机上NFC backup属性的VMKernel网卡IP地址。</p>
</div>
<div class="section"><h4 class="sectiontitle">可能原因</h4><p>使用Hot-Add/NBD/NBDSSL传输模式时，如果虚拟机所在ESXi主机配置了NFC backup属性的VMKernel网卡，NFC流量会转发到该专用网卡上。客户端所在主机与该网卡IP地址不连通，导致VDDK调用失败，备份失败。</p>
</div>
<div class="section"><h4 class="sectiontitle">处理步骤</h4><p>客户端网络规划时，若目标虚拟机所在ESXi主机设置了NFC backup属性的VMKernel网卡，请确保客户端所在主机到该VMKernel网卡的网络连通。</p>
